Sanko?
I was told by a friend that Sanko chromoly dents easier than regular 4130 chromo. I was thinking about starting to save up for a new frame after I pick up the GT Bump this weekend. So, which is better, Sanko or American chromoly.

Alright I was just wondering. I love the Sputnic frames and but was kind of leery about the Sanko.
And I didn't feel like starting a new thread for something stupid, but who made the flourescent orange parts? It was Odyssey right? I can't find them anywhere.

This is a pretty funny discussion... you do know that 4130 is simply a designation number for steel right? All 4130 means is that the steel contains other elements in a defined percentage range.
As far as American vs. anything else goes, that is a goofy way of deciding on a bike frame. Name some tubing manufacturers that are well known in the cycling world, Reynolds (England), Columbus (Italy), Tange (Japan), Sanko (Japan), True Temper (US)....they all make all sorts of tubing that meets the criteria to be called 4130.
Sanko tubes are considered desirable as they are "drawn" tubes, meaning the tube was formed through a forging process rather than formed by rolling a sheet and welding it along the seam. Does that mean it dents easier, I doubt it. What would make a frame dent easier is how thin the tube wall is at the spot that gets hit. A butted tube is made lighter by having thinner walls in the middle and thicker at the ends where it is welded. So if you want a heavy frame that resists denting don't get butted tubes.
What is going to make more difference is the frame design and the welding, a poorly designed frame with bad welds and the best tubing available is still a piece of junk.

Thanks for the explanation andymac. Alright, now I'm not at all worried about it. I want to start to save up for a Sputnic frame.

Sanko things are usually cheaper than US. I rather have some guy put quality time than some sweatshop working person trying to make numbers.

Lol are you serious? Its cheaper because the labor is cheaper over there and they can get good quality steel for a better deal. Doesn't mean they do a bad job manufacturing it. it's probably 80% machine done. Its just as good.

That frame (Deathtrap) makes no mention of being butted at all and it is a bit heavier than much of the competition so there is a good chance that the tubing has the same wall thickness throughout, which should lead to a more dent resistant frame.
....even if it turns out it is made in a sweatshop in Greenland...
